Found ancient remains of a pregnant reptiles

Reptile could attack from a distance, before the attack, curving his neck with a length of about two meters.

An international group of scientists found that dinocephalians belonging to the same group as dinosaurs, birds and crocodiles, give birth to live young, not eggs. Experts have found that, after studying the fossil reptiles of the age of the 245 million years. A study published in the journal Nature Communications.

The study’s lead author Jun Liu (Jun Liu) noted that the abdomen of the ancient reptile were discovered in the embryo. This suggests that the archosaurs, there is no General limit for live birth. Due to the fact that modern birds and crocodiles reproduce by laying eggs, scientists believed about the existence of unknown biological obstacles to this.

Along with this they determined that gender of the offspring of cynocephalidae is genetically determined. Crocodiles and turtles in turn, this index depends only on the temperature of egg incubation.

Dinocephalian belong to the genus of protozanov of the family Tanystropheidae. Reptile that lived under water, distinguished by the fact that could attack from a distance, before the attack, curving his neck with a length of about two meters. During the attack, she was pushed to the side ribs, growing on the cervical vertebrae, extending neck and thus the quenching of the shock wave, which could warn the victim about the attack of a predator.
